BW100's electrical contact point resurrection spray? Cleaning spray!
There are many people who need to use the BW100 to solve the problem of not pressing the remote control or Nintendo joystick. So there are people who think that BW100 is an electrical contact revival spray for electrical products. Is it true?
The BW100 is sold under the name of the electrical contact revival spray, and its actual function is the washing spray.
This cleaning product has the following advantages and functions.
1. Nontoxic.
2. Wireless.
3. Volatile.
4. It has low viscosity, so it's easy to put it in a small area
5. Insulation.
BW100 is an organic solvent that can be washed by dissolving dust and oil. However, these dust removal and oil melting do not reconnect the disconnected electrical contacts.
Experts are already cleaning substrates or products with methane/ethanol, and the BW100 is a product developed for the safety and convenience of ordinary users.
Therefore, it is difficult to remove metal oxide films because there is no physical or chemical function.
For example, gold plating on the earphone terminal prevents the formation of an oxide film on the terminal and increases the lifespan of the terminal, and when the gold plating on the terminal is peeled off, contact failure begins to occur.
Most physical buttons, such as remote controls and Nintendo joysticks, resist these oxide films, and some low-end products do not work, so the buttons do not work in a short period of time.
A button on the remote control or a button on the mouse is a typical case, and a coating that hinders the formation of a basic oxide film is applied. Nevertheless, the coating of the button peels off during continuous use and gradually begins to work poorly afterwards.
The better reason to use WD40 instead of BW100 for dust cleaning of remote buttons is that WD40 basically has anti-corrosive function, which hinders the formation of subsequent oxide films.
If you invest a little more money, it's best to deal with it as below.
1) Remove the oxide film after using the corrosive WD40
2) Wash it with Bw100.
3) Add oil with anti-corrosive function.
However, it cannot be considered efficient to spend this amount of time or money on inexpensive TV remote controls.
In conclusion, BW100 is not a contact resurrection agent, but a cleaner. It doesn't remove the oxide film. WD40 is corrosive and removes the oxide film and provides some lubrication, but can ruin the electronic circuit with dust and corrosiveness.
For reference, the joystick tilt phenomenon includes Xbox, PlayStation, and Nintendo. However, from my experience, Xbox and PlayStation are problems of tension springs (the spring that holds neutrality at the bottom of the stick is old and cannot return to the center), and Nintendo seems to be a dust problem considering that products less than a year have occurred.
